The salivary system has two principal and accessory salivary glands, two principal and accessory gland ducts. The salivary gland and duct wall have a single layer of cuboidal cells. The duct lumen is surrounded by a thick intima layer. In the cytoplasm of the epithelial cells are seen vesicles. The gut includes fore, mid, and hindguts. The foregut consists of a long narrow tubular pharynx which opens into a slightly wider esophagus. The esophagus is thin walled and in turn opens into the midgut. The midgut has four regions (V1–V4). V1–V4 walls have a monolayered epithelium. V1 epithelium is double-nucleated. V1 cytoplasm contains numerous vesicles, secretory granules, spherocrystals, and cytoplasmic inclusions. Rod-shaped bacteria are seen in V4 lumen. The hindgut has pylorus and rectum. Malpighian tubules were attached in the pylorus. Malpighian tubules have a single-layer cuboidal epithelium. In their lumen, there are spherocrystals. The rectum wall has a monolayer of squamous epithelium and muscle layer. Numerous bacteria and uric acid crystals are seen in its lumen.</p>","PeriodicalId":47028,"journal":{"name":"Race & Class","volume":"32 1","pages":"1-13"},"PeriodicalIF":2.8,"publicationDate":"2022-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87108206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From December 2018 to June 2020, 17 patients with deep wounds who were admitted to the Affiliated Hospital of Zunyi Medical University met the inclusion criteria and were included in this study, including 7 males and 10 females, aged 12 to 72 years. The wound areas of patients after debridement were 7 cm×3 cm to 11 cm×7 cm. Two longitudinal lines were located through the midpoint of the armpit, the posterior superior iliac spine, and the protruding point of the sacroiliac joint, and three transverse lines were located 5, 10, and 15 cm below the midpoint of the armpit between the two longitudinal lines, i.e. two longitudes three transverses method, resulting in two trapezoidal areas. And then the thoracodorsal artery perforators in two trapezoidal areas were explored by the portable Doppler blood flow detector. On this account, a single or lobulated free thoracodorsal artery perforator flap or flap that carrying partial latissimus dorsi muscle, with an area of 7 cm×4 cm to 12 cm×8 cm was designed and harvested to repair the wound. The donor sites were all closed by suturing directly. The number and location of thoracodorsal artery perforators, and the distance from the position where the first perforator (the perforator closest to the axillary apex) exits the muscle to the lateral border of the latissimus dorsi in preoperative localization and intraoperative exploration, the diameter of thoracodorsal artery perforator measured during operation, and the flap types were recorded. The survivals of flaps and appearances of donor sites were followed up. &lt;b&gt;Results:&lt;/b&gt; The number and location of thoracodorsal artery perforators located before operation in each patient were consistent with the results of intraoperative exploration. A total of 42 perforators were found in two trapezoidal areas, with 2 or 3 perforators each patient. The perforators were all located in two trapezoid areas, and a stable perforator (the first perforator) was located and detected in the first trapezoidal area. There were averagely 1.47 perforators in the second trapezoidal area. The position where the first perforator exits the muscle was 2.1-3.1 cm away from the lateral border of the latissimus dorsi. The diameters of thoracodorsal artery perforators were 0.4-0.6 mm. In this group, 12 cases were repaired with single thoracodorsal artery perforator flap, 3 cases with lobulated thoracodorsal artery perforator flap, and 2 cases with thoracodorsal artery perforator flap carrying partial latissimus dorsi muscle. The patients were followed up for 6 to 16 months. All the 17 flaps survived with good elasticity, blood circulation, and soft texture. Only linear scar was left in the donor area. &lt;b&gt;Conclusions:&lt;/b&gt; The ","PeriodicalId":47028,"journal":{"name":"Race & Class","volume":"56 1","pages":"165-169"},"PeriodicalIF":1.9,"publicationDate":"2022-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11704497/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87268827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the only pieces of research based on the experiences of the policed and their testimonies, the report suggests that policing during the Covid-19 pandemic undermines public health measures whilst disproportionately targeting Black and Minority Ethnic communities in the UK. The authors raise concerns about the policing of the pandemic and show that racially minoritised communities have been most harshly affected – being more likely to be stopped by the police, threatened or subject to police violence and falsely accused of rule-breaking and wrong-doing. The report argues that lockdown conditions, new police powers, and histories of institutionally racist policing have combined to pose a threat to already over-policed communities and the most marginalised and vulnerable sections of society.","PeriodicalId":47028,"journal":{"name":"Race & Class","volume":"63 1","pages":"92 - 102"},"PeriodicalIF":2.6,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47161515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adom Getachew’s Worldmaking after Empire (2019) and Franklin Obeng-Odoom’s Property, Institutions, and Social Stratification in Africa (2020) draw on the Black Radical Tradition and stratification economics respectively to challenge mainstream understandings of racial hierarchies. After first outlining the strengths and key insights of each book, the author discusses how they could be expanded in a more radical manner, along the lines of anti-colonial, decolonial and black Marxism. She argues that in order to understand how racial hierarchies are connected to the development of capitalism, further engagement with radical scholarship that sees race and class as co-constituted would be required.","PeriodicalId":47028,"journal":{"name":"Race & Class","volume":"63 1","pages":"103 - 108"},"PeriodicalIF":2.6,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44419590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is a global phenomenon, with US power at the centre preying on global markets through the process of digital colonialism. Mainstream antidotes to the ills of Big Tech and digital capitalism are US/Eurocentric and revolve around a collection of liberal and progressive capitalist reforms, including anti-trust, limited privacy laws, unionisation of Big Tech, algorithmic discrimination and content moderation – all of which are conceived within a capitalist framework which ignores or neglects digital colonialism and the twenty-first century ecological crisis, despite their analytical and moral centrality to contemporary political economy. This author argues that a combination of political, economic and social alternatives based on a Digital Tech Deal are needed to turn the tide against digital colonisation, entailing the socialisation of knowledge and infrastructure; passing socialist laws that support digital socialism; and new narratives about the tech ecosystem. These solutions are to be nested within an anti-colonial, eco-socialist framework that embraces degrowth to ensure environmental sustainability and socioeconomic justice.","PeriodicalId":47028,"journal":{"name":"Race & Class","volume":"63 1","pages":"63 - 84"},"PeriodicalIF":2.6,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46404759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
